Colesevelam (Welchol) has fewer patient side effects. Colesevelam (Welchol) may be taken with statins, digoxin, and warfarin. Less constipation, bloating, cramping, and flatulence is reported. Patients with hyperlipidemia are frequently taking statins, digoxin, and/or warfarin. Less interference with these being absorbed is easier for patient medication routines. Colesevelam (Welchol) is dosed once or twice a day with a meal. Colesevelam (Welchol) is to be taken with meals in order to bind with bile in the gastrointestinal tract. Colesevelam (Welchol) is the only bile-acid sequestrant which does not significantly block absorption of important fat-soluble vitamins (A, D, E, and K).

The nurse prepares to administer colesevelam (Welchol) to a patient. The nurse knows that which statement is true regarding Colesevelam (Welchol)? Colesevelam (Welchol) has fewer patient side effects. Colesevelam (Welchol) is dosed once per week. Colesevelam (Welchol) may be taken with statins, digoxin, and warfarin. Colesvelam (Welchol) may be taken on an empty stomach. Colesevelam (Welchol) reduces absorption of fat-soluble vitamins (A, D, E, and K).

Bile-acid sequestrants powders are difficult to mix in liquids. Lifestyle management is important, in addition to bile-acid sequestrants, in the treatment of hyperlipidemia. Maintaining good bowel habits facilitate the effectiveness of bile-acid sequestrant treatment. Bile-acid sequestrants are not soluble in water; therefore, patient compliance may be reduced with the powder form of bile-acid sequestrants. Exercise and a diet reducing saturated fats can more actively involve patients in their choices of lifestyle management. Bile-acid sequestrants bind with cholesterol in the small intestine and are excreted in the feces. Bile-acid sequestrants are considered adjunctive therapy for modifying cholesterol. Bile-acid sequestrants alone average a 20% reduction in LDL (low density lipoproteins). Combined with a statin LDL cholesterol can be reduced up to 50%.

The nurse reviews the physician's order for a bile-acid sequestrant to be administered to a new patient. Which statements are specific to bile-acid sequestrant medications? Bile-acid sequestrants powders are difficult to mix in liquids. Bile-acid sequestrants are the main drug of choice for treating hyperlipidemia. Lifestyle management is important, in addition to bile-acid sequestrants, in the treatment of hyperlipidemia. Bile-acid sequestrants are not combined with statin medications. Maintaining good bowel habits facilitate the effectiveness of bile-acid sequestrant treatment.

Statin drugs Oral anticoagulants Combining gemfibrozil (Lopid) with a statin is not recommended due to increased risk of rhabdomyolysis. Gemfibrozil (Lopid) can enhance the action of oral anticoagulants, thus careful dosing of warfarin (Coumadin) is required. Antibiotics are not enhanced by the use of fibrates. Antihypertensive agents may be combined with fibric acid derivatives. Insulin may be used with fibrates.

Separate taking bile-acid sequestrants by one hour before or four hours after taking thyroid hormones. Bile-acid sequestrants bind to and decrease the absorption and hence the effectiveness of Thyroid hormones (Synthroid, Levoxyl) Bile-acid sequestrants need to be taken with a meal, not at bedtime. Bile-acid sequestrants bind to and decrease the absorption and hence the effectiveness of Warfarin (Coumadin). Verbally teaching the patient and family members along with detailed printed instructions increase patient understanding about bile-acid sequestrant medications and compliance.

Which nursing instruction should be given to the patient taking a bile-acid sequestrant? Take bile-acid sequestrants at bedtime. Separate taking bile-acid sequestrants by one hour before or four hours after taking thyroid hormones Warfarin (Coumadin) may be taken at the same time as bile-acid sequestrants. Prescription bottle labels provide all instructions for taking bile-acid sequestrants.

The main response to bile-acid sequestrants is a reduction in LDL (low density lipoproteins). The mechanism of action is binding of bile acids to cholesterol in the intestine creating insoluble cholesterol excreted through the feces. The HDL (high density lipoproteins) does not decline in response to bile-acid sequestrants. VLDL (very low density lipoproteins) may increase in some patients who have high VLDL levels before with bile-acid sequestrants and are therefore not the drug of choice. The therapeutic response to bile-acid sequestrants begins in the first week of therapy and becomes maximal (about a 20% drop) within about a month.

Which statement best describes the response to bile-acid sequestrants? The HDL (high density lipoproteins) declines 10% in the first week of treatment. In patients with high VLDL (very low density lipoproteins), bile-acid sequestrants are a good first drug to consider. The main response to bile-acid sequestrants is a reduction in LDL (low density lipoproteins). The therapeutic response to bile-acid sequestrants begins in the first month of therapy and becomes maximal (about a 35% drop) in about three months.

Colesevelam (Welchol) can help control hyperglycemia in patients with Type 2 diabetes. Colesvelam (Welchol) was FDA (Federal Drug Administration) approved in 2008 for adjunctive therapy of Type 2 diabetes. Colesvelam (Welchol) must be taken with a meal to provide a food bolus in the intestine for the binding action with cholesterol. Colesvelam (Welchol) does not significantly reduce the absorption of warfarin (Coumadin) and may be safely prescribed when needed for anticoagulation therapy. There is no known interaction with OTC (over the counter) cold medications and Colesvelam (Welchol).

Warfarin (Coumadin) should not be prescribed for a patient taking Colesvelam (Welchol). Colesevelam (Welchol) can help control hyperglycemia in patients with Type 2 diabetes. OTC (over the counter) cold medications are more effective when taken with Colesvelam (Welchol).

Bile-acid sequestrants are biologically inert Bile-acid sequestrants do not initiate a response or interact when introduced to biological tissue. Bile-acid sequestrants are not attacked by digestive enzymes because they are biologically inert. Bile-acid sequestrants are insoluble; therefore, they pass directly in the feces without retention in the intestines. Bile-acid sequestrants have no known effect on the urinary tract.

Which statement describes the properties of bile-acid sequestrants? Bile-acid sequestrants are biologically inert. Bile-acid sequestrants can be attacked by digestive enzymes. Following oral administration, bile-acid sequestrants need to be retained in the intestines for a week before being excreted in the feces. Bile-acid sequestrants may cause urinary incontinence.

Bile acids secreted into the intestines are reabsorbed and reused. The bile-acid sequestrants bind cholesterol in the gastrointestinal tract. The bile-acid sequestrants result in an increase in the number of LDL receptors on the liver surface The normal bile acids are reabsorbed from the intestines and reused by the liver. The bile-acid sequestrants bind cholesterol in the gastrointestinal tract and prevent the resorption of the bile from the small intestine. This insoluble bile, bound to cholesterol is excreted in the feces.Insoluble bile cannot return to the liver, which causes the liver to compensate for the loss of cholesterol by increasing the number of LDL receptors on its surface. Bile is excreted via the gastrointestinal tract not kidney. Bile-acid sequestrants usually lower LDL cholesterol by 10%-20%, not increase.

Which statement(s) describe(s) the pharmacodynamics of bile-acid sequestrants? The bile-acid sequestrants excrete bile in the urine. Bile acids secreted into the intestines are reabsorbed and reused. The bile-acid sequestrants bind cholesterol in the gastrointestinal tract. The bile-acids sequestrants usually raise LDL cholesterol by 10%-20%. The bile-acid sequestrants result in an increase in the number of LDL receptors on the liver surface

Bile acids in the intestine are normally reabsorbed and reused. Bile-acid sequestrants form an insoluble complex with bile acids, which prevents reabsorption and accelerates their excretion. Bile acids in the intestine are normally reabsorbed and reused in the liver. Bile-acid sequestrants form an insoluble complex with bile acids, which prevents reabsorption and accelerates their excretion. Bile acids are secreted from the liver into the intestine. The liver replenishes bile acid from cholesterol in LDL (low density lipoprotein) cells in the plasma. The liver has specific receptor sites for LDL (low density lipoproteins) cholesterol which reduces the total LDL cells in plasma circulation.

Which statements are correct regarding the pharmacodynamics of bile-acid sequestrants? Bile acids are secreted from the pancreas. Bile acids in the intestine are normally reabsorbed and reused. Bile-acid sequestrants form an insoluble complex with bile acids, which prevents reabsorption and accelerates their excretion. The liver replenishes bile acid from cholesterol in HDL (high density lipoprotein) cells in the plasma. The liver has receptor sites for HDL (high density lipoproteins) cholesterol.
